This project, subsidized by CDTI in the R&D&I call, has as its main objective the decentralized production of hydrogen by reforming landfill biogas. The novelty of the project is that the catalyst must carry out mixed reforming since landfill biogas has oxygen, carbon dioxide and water in its composition. Steam reforming, autothermal reforming and dry reforming will be carried out in the same catalytic bed. In addition, feasibility studies will be carried out with different biogas compositions to evaluate the flexibility of the process with respect to the type of feed, as well as the economic viability of the process.
It is therefore about making hydrogen production economically competitive and sustainable based on the principles of the #CircularEconomy. With this, the biogas generated in the digestion of waste is valorized towards other uses of energy, not only towards the application in electrical energy.
To achieve this, the following tasks are carried out:
- Selection of a method and material for biogas cleaning.
- Synthesis of a reforming catalyst.
- Identification of the best operating conditions of the catalyst in Mixed reforming.
- Validate the stability of the solution using real landfill gas as feed.
- Simulation and model of the process for the design of future scales.
This project is being developed at the Montemarta Cónica Comprehensive MSW Treatment Center, located in Alcalá de Guadaíra (Seville), where continuous tests are being carried out with real biogas. Currently, continuous work has been achieved for more than 1.500 hours.
The development of this project seeks to create a scalable prototype to produce hydrogen. When a stable technology is achieved, ENERSUR will look for potential clients in the market of biogas producers, trying to offer the technology as an alternative to the traditional uses of biogas. With the results obtained so far, and extrapolating to a first commercial installation, it is estimated that it will be possible to reach production costs around €2/kg.
